摘要： An apparatus, system, and method are disclosed for automatically and transparently managing addresses in an arbitrated loop network. An arbitrated loop network switch is programmed with an address map and configured with the necessary modules to monitor an address assignment process and associate soft assigned addresses claimed during the address arbitration process with physical slot addresses. In one embodiment, the address fields of packets addressing a specific physical slot are changed (in route) to the soft address assigned during the address arbitration process. The entire process may be transparent to the rest of the network and to users. The present invention facilitates maintaining a physically ordered addressing scheme despite any soft addressing that occurs during loop initialization.

摘要： An indicator light, such as an LED, for a computer disk drive module is controlled via an external controller. The disk drive module monitors a disk drive and determines a desired state of the LED, such as on, off or flashing, to indicate a status of the disk drive. The disk drive module provides a modulated signal carrying data that identifies the desired state on a path coupled to the indicator light and a terminal that is accessed by the external controller. The controller implements an algorithm for driving the indicator light, where the algorithm receives, as a first input, the desired state determined from the demodulated signal and, as a second input, information obtained from monitoring the disk drive module. The controller itself may obtain this information or receive it from a higher-level system controller.

摘要： A firmware update system includes a high-level management device implementing high-level management software application that selects a redundant embedded processor as a master sub-system. Firmware update images are transmitted to the master sub-system over a primary communication path. The master sub-system re-distributes the firmware update images to other associated redundant embedded processors over secondary communication paths. This reduces communication-bandwidth utilization over direct communication paths between the high-level management system and the other associated redundant embedded processors.

摘要： An apparatus, system, and method are disclosed for detecting and reporting network mis-cabling. One embodiment of the apparatus includes a detection module, a comparison module, and a cabling connection module. The detection module is configured to detect a new connection at a network switch. The new connection is formed by physically connecting a network cable to the network switch, at one termination, and to another network device, at another termination. The comparison module is configured to compare the new connection to a connection rule, where the connection rule defines either a legal cabling connection or an illegal cabling connection. The cabling connection module is configured to control whether or not the new connection is inserted into the data network or maintained isolated from the data network. Certain implementations of the present invention beneficially allow a new network connection to be verified prior to logical insertion so that potential mis-routing of data and other mis-communications within the data network may be avoided.

摘要： Systems, methods and a computer program product are provided to permit the identification of all of the devices of a specified domain in a multi-domain environment. All communication among the domain devices is in-band having the advantage that no additional cabling is required. A control center between host devices and the domains receives an in-band command from an initiating device in a specified domain, the command being transmitted in response to the activation of a triggering device on the initiating device. Upon receipt of the command, the control center broadcasts an in-band command to each of the other devices in the domain directing the other devices to activate an indicator on each of the other devices. With the indicators on the devices in the specified domain activated, an administrator is able to identify those devices and thus focus his search for the faulty device only on those devices within the domain.

摘要： In a RAID storage system, a parity value is generated. The storage system includes a RAID adapter, a plurality of disk array processors managing corresponding sets of RAID storage drives, and a connecting fabric. The RAID adapter initiates a parity generation operation, parallel instructions are dispatched for the array processors to each generate a partial parity value from data blocks on drives on respective managed RAID storage drives, the partial parity value is received in the RAID adapter from each array processor, and the partial parity values are combined in the RAID adapter to generate a complete parity value. The parity value may be an actual parity block to be stored on a hard disk drive or may be a reconstructed data block in the event of a failed drive.

摘要： A high density storage enclosure includes a plurality of storage devices, such as hard disk drives, positioned within a cooling airflow. Data to be stored to a storage device is received and a determination is made as to the expected usage of the data relative to other data stored on devices within the enclosure. The data is stored in a device having a position within the airflow relative to the source of the airflow in direct relationship to the relative expected usage of the data. Thus, data having a higher expected usage is stored in a device closer to the airflow source relative to other data having a lower expected usage and data having a lower expected usage is stored in a device farther from the airflow source relative to other data having a higher expected usage. Additionally, data may be dynamically relocated based upon actual usage.

摘要： A storage system includes a RAID adapter, disk array switches, sub-processors, and hard disk drives (HDDs). A disk-related operation is initiated in the RAID adapter. The RAID adapter dispatches a command to a disk array processor (or sub-processor) in an enclosure for the processor to perform the operation on one or more drives. The adapter may dispatch the command to a processor in a single enclosure through a disk array switch or to processors in multiple enclosures through switches in the upstream enclosures. The adapter is then free to perform other functions. The processor commences the specified operation on one or more selected drives, either sequentially one at a time or sequentially more than one (or all) at a time. Upon completion of the operation, the results are transmitted by the processor and received by the adapter. Thus, by offloading the task to the distributed sub-processors, the burden on the RAID adapter is significantly reduced, system bandwidth usage is reduced, and access to other drives within the enclosure (as well as within other enclosures) may be maintained. Tasks which may be offloaded in such a manner include, but are not limited to, drive firmware updating, drive scrubbing and secure data erasure.

摘要翻译： 存储系统包括RAID适配器，磁盘阵列交换机，子处理器和硬盘驱动器（HDD）。 磁盘相关操作在RAID适配器中启动。 RAID适配器将命令分配给机箱中的磁盘阵列处理器（或子处理器），以便处理器对一个或多个驱动器执行操作。 适配器可以通过磁盘阵列交换机将命令分派到单个机柜中的处理器，或通过上游机箱中的开关将命令分配到多个机箱中的处理器。 然后适配器可以自由执行其他功能。 处理器在一个或多个选定的驱动器上开始指定的操作，一次一个依次依次执行，或者一次连续执行多个（或全部）。 操作完成后，结果由处理器传送并由适配器接收。 因此，通过将任务卸载到分布式子处理器，RAID适配器的负担显着降低，减少了系统带宽使用，并且可以维护对外壳（以及其他机箱内）的其他驱动器的访问。 可以以这种方式卸载的任务包括但不限于驱动固件更新，驱动器擦除和安全数据擦除。
